OILER 'FOR PRESSURE-FLUIS TOOLS'.

Specification of Letters Patent.. afilatented Apr, 18, 1911,

Application filed June 24, 1910. Serial No. 5683684.

To all' whom 'it may concern:

Be it; known thalt l, Lewis' C. Barnes, a citizen of the United States, and resident of Johannesburg, Transvaal, have invented a -new and uset'ul l1n]no\e1nent in Oilers for Pressure-Fluid Tools` of u'hiehy the following is a specification.

The object. of my invention 1s to provide an' oilei-"for fluid' pressure operated tools,

, the objectbeing to provide a devie in which the oil may he fed in 'the required quantities directly to the Vsupply side of the tool controlling valve, the oilerserving also as arotat'ing 'handle for the tool.

-A further object of my invention is to provide the oiler with a porous plug arranged to serve the double purpose of regulating lthe flou' of oil and ot' cleansing the oil of anyV grit or dirt it may contain, before .permitting it, to be; fed to the tool.

A practical embodimentof the invention s represented in the accompanying draw- 'lngsi 1n which,

Figure 1 represents in side elevation,y so lunch of a iluid pressure actuated vtool as will give afclcar understanding of the location of my improved oiler thereon. Fig.

2 isa similar vieu* taken at right angles to Fig. l. F.ig. 3 represents the same partially' infsi'de elevationz and partially in longitui oiler 'in longitudinal central section -on an enlarged scale. Fig; is a section taken in the plane of th(` hue A--.-\ of Figflll. Fig. G

isA a section taken in theplane of the` line B'-"-B'of Fig. 4, and Fig. 7 its a section taken l inthe plane ofthe -line-(l--Cf4 oFig. 4.,

`. Injthe fluid .pessure actuated tool herein represented, the tool controlling valve is de- -fefed c linder by 5.and. its piston by 6;

noted vby "1, the, valve chest by 2, the val-ve plate by'.I the tool cylinder by 4, the air A suitab e manually operated controlling valve 'T'iSPIOVdedV-in theralve chest 2 for controllin `the admission .of the motive-fluid from t e' supply pipe vSgt-o eitherV the air -feed cylinder 5 or' the valve 1 or to both at pleasure. The pressure fluid supply passage leadiiiglfrom he manually operated valve- 7 to the tool controlling valve-1, is denoted by 9, andthe discharge passage leading from the tool controlling valve l mosphereis denoted by 10.

Proceeding to desclibe my improved oiler,

the casing 11 of the oiler. forms the rotating handle for the tool, which handle is secured firmly in the valve chest 2, as follows. The

to external atl inner end of the handle 11 is provided with a screw-threaded ortion 12 and adjacent thereto the handle 1s tapered, which tapered portion is-adapted to enter a tapered seatforined in the valve chest 2. A nut 13 is engaged With the screw-threaded end 12 of the handle 'exterior to the valvechest, which nut as it is screwed home. will draw the tapered portion of, the handle snugly down in its tapered seat in the valve chest, thus forming a tight joint'between the two and obviating the necessity of a threaded 'connection between the handle and the tool. The interior-,of this handle or casing 11.. is provided with an enlarged boreofr 'chamber 14 and asma'llen bore 15' leading fromy t-he inner 4end `of the chamber 14 to apgintne-ar--- the inner end of the casing. The inner end ofthe-reduced bore 1.5 .is provided withone or inorez-la-tral passages 16 openinginto a circumferential `groove 17 1n the ca-slng. This groove 17 1s in open`commun1cat1on .with a'passage 18 leading tothe pressure 'fluid' Asupply passage 9 in the valve `chest. 2,

het-Ween the valve 1 and the manually operated controlling valve' 12. Vithin-the chamber 14, I locate a porous g, plug-1 19. lthrough which asmall tube 20 'is passedp-trhe inner end of which tubepis open and the `oi'iter'end of, which tube is closed. lu the space Within the chamber 14, vbetween cap 21, the'tubeQO 4is provi ed with one or more minute holes, through` its walls b y means ofavhich pressure, from within the .the outer end of the" porous lug 19 and -the .valve chestatflthe supply side ofthe valve `1 l =maybe`perxhittd 'to' pass into the ehailber 14. This porous plugll)v may'he f ol'md i'nany vsuitable manner as for inatandayby rolling a strip ofxbrass wire netting and a stri offabric, such as flannel'or cotton, toge r around the tube 20.

-- In operation, the cap 21 1s vremoved and the casing or rotatin handle 11 is filled .ithoiLl The cap 21 1s then replaced. As

lie manually operated controllm 4valve 7 is opened -to eratethe.- tool, t eoil is diawn through t e porous plug, the reduced 1p bore-15, the ptzftbl and passage 18 into the' 'su 'ply passag This is accomplished. in eit "or'both ofthe follovvinor methods; by the eiluctuations in pressure diie to the o .eration of the tool; or-by the pressure in't e 1li chamber 14, as follows. The oil in the cham- .ber 14^between the `porous plug 19 and the cap 21 is soon absorbed in the porous plug T19. Ylhen the manually operated valve 7 is opened the motive fluid is admitted to the 20..-passage 9'and a portion ,of the motive fluidl passes through the tports and passages 18, 17, 16, 15, tube -an the small holes 22 into the chamber 14 and fills said chamber v111 with compressed mot-ive fluid. When the .25 valve 7 is closed the pressure of the motive fluid in. port 9 at -once falls 'below that in 'chamber 14 result-ing in a rush of motive fluid from 14 to 9. A portion will pass through the ports and' passages 22, 20, .15, I, 17 and 18, but owing to the minute size of. port 22, the greater portion will pass through the porous plug 19 and ports and passages' 15, 16, 17 and 18- taking up a smalll amount of oil in its passage through the '35V porous plug 19. Thus the porous plug serves the double purpose 'of regulating the flow of oil to the luid supply passagey 9.

, -where 'it may pass from thence throughthe tpol and also of cleansing the oilof any grit 40 or dirt which it may. contain before it is fed to the said supplyfpassage The rotating Ahandle for the tool also serves asthe oiler complete, thus obviating the necessity ofl I its piston, a piston operating valve, itsv chest, a. manually operated throttlev valve p seated in said chest for controlling the ad` missionof pressure fluid to. said piston operating valve .and means for feediitg-ol to the supply side of the pistonopera'ting valve i; between it andthe throttle valve.
